CORPORATION OF NEW YORK BALANCED DISK WHEEL Application lediAugust 29, 1927. Serial No. 216,183.

This invention relates to disk wheels of the type ordinarily used on automotive vehicles'.-

It is an object of the present invention to simplify and chea en the manufacture of disk wheels by making all the necessary parts of the disk from a single stamping, and this Without changing the-size or shape of the sheet of metal from which the ordinary disk isy stamped. In stamping the disk from the ordinary blank two diametrically positioned projecting sectors are included with the disk. One of these sectors has an opening for the valve stem and a depressed portion to form an interlocking means with the rim. The second sector is larger and has sufficient eX- cess metal to compensate for any dierence in weight caused by the valve stem and the` locking lug. This structure will give a balanced effect to the wheel, or give a counterbalanced wheel'.

J In the drawings:y

Figure l is a side elevation. y Figure 2 is a section on the line 2-2 of Figure 1.

Figure 3 is a reduced plan view of a square sheet of metal out of lwhich the disk is stamped, showing the shape of the vmetal used and the part discarded.

Referring to the drawings, we have illustrated on a reduced scale in Figure 3 a square sheet of metal, the numeral 10 indicating plained below. A hole 16 is punched in the the blank cut out and to be pressed into the disk illustrated at 11 in Figure 2. Two diametrically opposite sectors 12 and 14 are provided in the blank at opposite corners, the lower one being the larger of the two, as exsector 14 for reception of the valve stem. The numeral 18 indicates a circumferential portion which is depressed, as shown in Figure 1, andin'this depression fits the driving or locking lug 19 on the inner side of the rim, ythe lug being held to the rim b means of rivets or pins 22. If desired, t e driving lug may be a depressed portion of the rim fitting the depression 18.

The rim 20 is provided on its inner surface with a flange 24 having a surface corresponding to that of a thin section of a truncated cone, and this surface fits against the corresponding surface 23 on the periphery of the disk. Lugs 26 fit against the flange 24 and the rim of the disk and are held in position by bolts 28. 4

The sectors add some strength tothe finished disk and in addition the upper sector serves to hold the rim and disk against relative rotation, by means of the depression 18 fitting the locking lug 19. The lower sector is larger than the upper in order to counterbalance the added weight'of the locking lug and valve stem.

We claim:

1. In a disk wheel, a disk provided with a marginal fiange to receive a tire carrying rim and diametrically opposite projecting f portions on said flange, one of said portions being provided with an opening to receive the valve stem of the tire and the other of said portions having aweight sufiicient to counterbalance the weight of said first mentioned Aportion and the valve stem.

`2. In a disk wheel, a disk provided with a marginal flangeto receive a tire carrying rim having a locking member on its radially inner face and diametrically opposite projecting portions on said flange, one of said portions being provided with an openingto receive the valve stem of the tire and a recess to receive the locking member and the other of said portions having a weight sufficient to counterbalance the weight of said first mentionedportion, the valve stem and the locking member. i
